Advantage Lithium Corp. announced that the updated resource estimate for the Company's Cauchari Project in Jujuy, Argentina has more than doubled from the previous resource announced in May 2018. The updated resource is based on the results of the Phase II and Phase III drilling programs. The update, prepared by FloSolutions SpA, has increased the resource to a volume of approximately 1,800 million cubic metres of brine at an average concentration of 476 mg/l lithium, for 4.8 Mt of Lithium Carbonate Equivalent (LCE) in the Measured and Indicated Categories and approximately 600 million cubic metres of brine at an average grade of 473 mg/l lithium for 1.5 Mt of LCE in the Inferred category. The drilling program has expanded the resource at the Cauchari Project to 4.8 Mt of LCE of Measured+Indicated Resources contained in 1.8 km3 of brine and 1.5 Mt of Inferred Resources contained in 0.6 km3 of brine. The resources have been broken into six different geological units which are classified between Measured, Indicated and Inferred resources, with the classification reflecting differences in the level of available sample information. The key areas of the resource for future brine production are the Archibarca Fan and the SE Sector of the Project. The Archibarca Fan resource consists of 1.0 Mt of LCE as Measured Resources at 564 mg/l lithium. The Measured and Indicated Resources in the SE Sector, mostly contained in the Clay and Halite units, amount to approximately 3 Mt of LCE at 481 mg/l lithium. The extraction characteristics of the Archibarca Fan and SE Sector have been confirmed by the 30 day pumping tests in each area during the Phase III Program in 2018.
